Daily Mail Diary Editor Richard Eden believes the King “didn’t intend” to give his brother the title as part of his plans to “slim down” the royals.
He told the Palace Confidential talk show: “But then, when Harry and Meghan started using the prince and princess titles for their children, it became clear this wasn’t going to happen and then King Charles could hardly justify not giving Prince Edward the title he’d been promised by their parents.
“It was a big deal and I really think that was behind it.”
However he added that Charles has a trick up his sleeve to get back at his youngest son.
By insisting that the Edinburgh title reverts to the Crown when Edward dies, rather than it passing onto his children, Harry will be unable to hand down his own title.
He added: “I have heard it said that part of the reason is that the King wants to stop Archie inheriting that title the Duke of Sussex. So this might be part of that, so he has now set that precedent.
“The problem is, that he’d have to do it with all the royal dukes so he really wouldn’t want to do that to the very well respected Dukes of Gloucester and Kent.”
